  However, in recent years, the manufacturing apparatus disposed in the clean room has further increased in size. Therefore, if an attempt is made to construct a large space using the above-described clean booth, the load of the air purification device provided on the ceiling of the clean booth becomes excessive, so the clean booth needs to be suspended from the floor slab on the upper floor. There is. As a result, there is a problem that it is difficult to move the clean booth to an arbitrary position, and the production line cannot be changed flexibly.

  An object of this invention is to provide the clean booth which can construct | assemble a large space and can be arrange | positioned in arbitrary positions.

The clean booth according to claim 1 is a clean booth provided in a clean room and having an internal space, and a pair of booth bodies provided along the internal space and opposed to each other with the internal space interposed therebetween , Each booth body includes a housing, a sock duct made of a non-woven fabric extending from the upper portion of the housing to the internal space, and an interior of the housing. An air purifier that is provided and increases the air cleanliness of the air taken from the outside and supplies it to the sock duct, a column that is provided at the lower end of the housing and can be expanded and contracted in the vertical direction, and provided at the lower end of the column A pair of telescopic frame members that connect the upper end sides of the booth main body, and the space between the frame members and the inner space. A cloth-like ceiling member for covering, characterized in that it comprises a cloth-like pair of wall members covering the side surfaces of the internal space hanging downwardly from each of said pair of frame members.

According to the present invention, since the air purification device is built in the booth body, since the air purification device is not provided on the ceiling portion of the clean booth as in the conventional case, the clean booth is suspended from the floor slab on the upper floor. There is no need. Therefore, the clean booth can be easily arranged at an arbitrary position.
In addition, the clean booth can be stored compactly by removing or folding the sock duct from the booth body.
In addition, by connecting a plurality of clean booths in the width direction, a large space can be constructed by connecting the internal spaces of the clean booths.

According to the present invention, since the support column that can be expanded and contracted in the vertical direction is provided, the height of the internal space can be easily adjusted by expanding and contracting the support column.
In addition, since the casters are provided at the lower end of the column, the clean booth can be easily moved by simply pushing the booth body manually.

By the way, when a single booth body is used, the sock duct is extended to the opposite side of the booth body. Then, the wind speed of the air blown from the proximal end side of the sock duct becomes higher than the wind speed of the air blown from the distal end side, and there is a possibility that the wind speed of the air flowing through the internal space may vary.
However, according to the present invention, since the clean booth is configured including the pair of booth bodies arranged opposite to each other, the length of the sock duct can be shortened as compared with the case where the booth body is a single unit, and thus the internal space flows in the interior space. Air velocity can be made uniform.

According to the present invention, since the ceiling member and the wall member are cloth-like, the ceiling member and the wall member can be easily removed. Therefore, for example, the above-mentioned large space can be constructed more easily by removing the wall member and connecting a plurality of clean booths.
Moreover, for example, if the ceiling member or the wall member is removed and the clean booth is disposed in the sealed space, the air cleanliness of the entire sealed space can be increased.

  According to the present invention, since the pair of frame members can be expanded and contracted, the length of the internal space can be easily adjusted by expanding and contracting these frame members.

The clean booth according to claim 2 is characterized in that the upper half of the sock duct does not transmit air and the lower half transmits air.

  According to the present invention, the upper half of the sock duct has a structure that does not transmit air. Therefore, since air with high cleanliness does not escape from the upper side of the sock duct into the internal space, air can be supplied efficiently.

  According to the present invention, since the air purification device is built in the booth body, since the air purification device is not provided on the ceiling portion of the clean booth as in the prior art, the clean booth is structured to be suspended from the floor slab on the upper floor. There is no need. Therefore, the clean booth can be easily arranged at an arbitrary position. In addition, by connecting a plurality of clean booths in the width direction, a large space can be constructed by connecting the internal spaces of the clean booths.

It is a perspective view of the clean booth which concerns on the 2nd modification of this invention.

FIG. 1 is a perspective view of a clean booth 1 according to an embodiment of the present invention.
The clean booth 1 is provided in a ceilingless clean room and has a rectangular parallelepiped internal space S. The clean booth 1 increases the air cleanliness of the internal space S.

  The clean booth 1 includes a pair of booth main bodies 10 provided along the internal space S, and a partition unit 20 that partitions the internal space S and the outside. The pair of booth main bodies 10 are disposed to face each other with the internal space S therebetween.

FIG. 2 is a partial cross-sectional view of the booth main body 10 of the clean booth 1.
The booth main body 10 is provided with a wall-shaped casing 11, three sock ducts 12 extending horizontally from the upper portion of the casing 11 toward the internal space S, and the interior of the casing 11 for taking in air from the outside. An air purification device 13 that increases the air cleanliness and supplies it to the sock duct 12 and a pair of moving devices 14 provided on both sides of the lower end edge of the housing 11 are provided.

  The moving device 14 includes a support column 141 provided at the lower end edge of the housing 11 and capable of extending and contracting in the vertical direction, and a caster 142 provided at the lower end of the support column 141.

  The housing 11 is formed with a suction port 112 that opens to the opposite side of the internal space S, that is, toward the outside of the clean booth 1.

The air purification device 13 includes a fan 131 provided in the casing 111 and connected to the suction port 112, and a chamber 132 connected to the fan 131.
Inside the chamber 132, a rectifying plate 133 and a filter 134 are provided.
In this embodiment, the filter 134 is provided, but the filter 134 is appropriately selected according to the air cleanliness required for the clean booth 1.

FIG. 3 is a cross-sectional view of the sock duct 12.
The sock duct 12 has a cylindrical shape made of a nonwoven fabric. The upper half of the sock duct 12 does not transmit air, but the lower half has a structure that transmits air. One end side of the sock duct 12 is connected to the upper end side of the chamber 132.
A material having a filter function may be used as the sock duct 12. In this case, it is conceivable that a filter in the chamber is selected in consideration of the filter function of the sock duct, and in some cases, no filter is provided in the chamber.

  Returning to FIG. 1, the partition portion 20 includes a pair of frame members 21 that connect the booth bodies 10 to each other, and a cloth-like ceiling member 22 that is spanned between the frame members 21 and covers the upper surface of the internal space S. And a pair of cloth-like wall members 23 that hang downward from each of the pair of frame members 21 and cover the side surfaces of the internal space S.

The frame member 21 is a metal rod-shaped member that connects both sides of the upper end edge of the booth main body 10 and has a structure that can expand and contract in the axial direction.
The ceiling member 22 and the wall member 23 are highly transparent curtains and have a structure that prevents air from passing therethrough. A gap is formed between the lower end of the wall member 23 and the floor surface.

The above clean booth 1 operates as follows.
That is, when the fan 131 is driven, air having a certain degree of cleanliness in the clean room is sucked from the suction port 112 and reaches the chamber 132. The air is rectified through the rectifying plate 133, dust is removed by the filter 134, and supplied to the sock duct 12. The air supplied to the sock duct 12 blows out from the upper part of the internal space S and flows downward. The air that flows downward is discharged to the outside of the internal space S through the gap at the lower end of the wall member 23.
In this way, the air cleanliness of the internal space S of the clean booth 1 is locally improved compared to the outside of the clean booth 1.

According to this embodiment, there are the following effects.
(1) Since the air purification device 13 is built in the booth main body 10, since the air purification device is not provided on the ceiling portion of the clean booth as in the prior art, the clean booth 1 is suspended from the floor slab on the upper floor. There is no need. Therefore, the clean booth 1 can be easily arranged at an arbitrary position.
Moreover, as shown in FIG. 4, by connecting a plurality of clean booths 1 in the width direction, the internal spaces S of the clean booths 1 can be connected to each other to construct a large space.
Moreover, the clean booth 1 can be stored compactly by removing or folding the sock duct 12 from the booth body 10.

(2) Since the support column 141 that can be expanded and contracted in the vertical direction is provided, the height of the internal space S can be easily adjusted by extending and contracting the support column 141.
Moreover, since the caster 142 is provided at the lower end of the column 141, the clean booth 1 can be easily moved by simply pushing the booth body 10 manually.

  (3) Since the clean booth 1 is configured including the pair of booth bodies 10 arranged opposite to each other, the length of the sock duct 12 can be shortened as compared with the case where the booth body is a single unit. The wind speed can be made uniform.

(4) Since the ceiling member 22 and the wall member 23 have a cloth shape, the ceiling member 22 and the wall member 23 can be easily removed. Therefore, for example, the above-described large space can be more easily constructed by removing the wall member 23 and connecting the plurality of clean booths 1.
For example, if the ceiling member 22 and the wall member 23 are removed and the clean booth 1 is arranged in the sealed space, the air cleanliness of the entire sealed space can be increased.

  (5) Since the pair of frame members 21 can be extended and contracted, the length of the internal space S can be easily adjusted by expanding and contracting the frame members 21. If the internal space S is lengthened, the sock duct 12 also needs to be lengthened. In this case, a metal fitting is attached to the frame member 21 and the sock duct 12 is suspended via this metal fitting.

  (6) The upper half of the sock duct 12 has a structure that does not transmit air. Therefore, since air with high cleanness does not escape from the upper side of the sock duct 12 to the internal space S, air can be supplied efficiently.

It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
For example, in this embodiment, although the partition part 20 was comprised with the frame member 21, the cloth-like ceiling member 22, and the cloth-like wall member 23, it is not restricted to this. That is, the partition portion may be an air curtain that partitions the internal space and the outside by the injected air.

Further, the length and width of the sock duct 12 may be set as appropriate.
In the present embodiment, a pair of booth main bodies 10 are provided. However, the present invention is not limited to this, and the booth main bodies 10 may be single as shown in FIG. In this case, for example, the frame member 21A is composed of a pair of support posts 24 having casters 25 that can be expanded and contracted in the vertical direction, a first connection member 26 that connects the upper ends of these support posts 24, and the upper ends of the support posts 24 and the booth. And a pair of second connecting members 27 that connect the main body 10. Further, the sock duct 12 is extended to the opposite side of the booth body 10, that is, to the vicinity of the first connecting member 26.
